Die Formed Graphite Rings
Die pressing graphite seals ensures a strong density and sealability without the use of fillers or binders. These pure graphite seals are reliable up to temperatures of around 430°C and are resistant to the majority of chemical media. We offer die formed graphite packing rings in any size.
Graphite/PTFE Gland Packings
Gland packing is usually provided on a roll and consists of interwoven yarns of a particular material, or set of materials, to form a square-section rope, used to seal various applications.
Graphite Sheeting and Strip
Graphite sheeting can be manufactured with stainless steel or nickel reinforcement, or as soft pure graphite sheet. Offered in multiple standard sheet sizes or cut to your specific size requirements. In addition to cutting and laminating graphite sheet, we can also offer graphite strip slit from rolls. These strips can also be provided with corrugated and self-adhesive options and are an ideal solution for valve packings where space is too limited to install a die formed graphite ring.
Graphite sheet is available in a variety of sizes and options, including:
- Tanged Graphite: Graphite sheet with a perforated stainless steel reinforcement.
- Stainless Foil: A thin sheet of stainless steel foil between layers of graphite.
- Pure Graphite: Non-reinforced pure graphite in soft sheet form. Available as thick as 12mm.
Spiral wound Gaskets
Spiral Wound Gaskets are a robust sealing product widely used across many industrial applications.
Spiral Wound Gaskets consist of a ‘V’ shaped metal strip spirally wound in combination with a soft filler
material - normally Graphite, PTFE or Mica depending on the application and customer specification.
Details:-
• Spiral Wound Gaskets are suitable for use across a wide gasket stress range and are able to seal fluid
pressures up to 400 bar and from cryogenic temperatures up to 1000oC.
• Available to suit ASME, DIN or JIS standard flanges or to special dimensions in materials to suit
mating flange.
• Available in bespoke sizes to suit vessel or exchanger applications.
• By combining different winding materials and metals, Spiral Wound Gaskets can be tailored to suit a
wide variety of operating conditions.
• The outer guide ring simplifies assembly and prevents blowout of the gasket.
• The gasket is easy to remove after service and does not cause any damage to the flange faces.
Soft Cut gaskets
Soft gaskets can be used across a wide range of applications and service conditions:-
• Compressed Non Asbestos Fibre (CNAF) & Rubber gaskets offer an affordable sealing solution and are often used for pressure testing lines or in low temperature/pressure applications.
• Graphite, PTFE and high specification Filled PTFE gaskets can be used where aggressive media is present from low to mid temperature ranges.
• High temperature materials are designed to withstand up to 1000 OC in low pressure applications.
• Standard size gaskets to B16.21/DIN/JIS gaskets to suit RF and Flat Face flanges or to bespoke dimensions can be produced quickly and efficiently.
Materials for soft cut gaskets
• Compressed Non Asbestos Fibre (CNAF) Grades.
• Graphite laminates – Stainless Steel Tanged and Reinforced Graphite.
• High Temperature gasket materials and laminates.
• PTFE & Filled PTFE.
• All types of Rubber including Commercial, EPDM, Neoprene, Nitrile & Viton/FKM
Bespoke Gaskets
As well as standard sizes, we can provide custom flat cut gaskets to your sizes or specific drawing. These may be simple joint rings, full face gaskets to accommodate bolt holes, or custom shapes to your drawing or brief. Using the latest CNC FlashCut technology, we offer a precise, high quality finish without compromising on lead time.
